ententes sa, iena crachn machine may be rmly securedlto flange 4: and composed of a vertical portion extending downwardly from the lied plate at the iront et the flange i to a point below the saine, and a horizontal portion extendi ing rearwardly-beyond the flange" and having its terminal enler ed and provided with a threaded opening or the reception of a thumb screw 6., The L-shaped arm of the clamp cooperates with the plate l to form a clamp yoke in which the edge of the table is securely held by the thumb screw. When the trarne is clamped to the table, it is rmly and securely fastened to the saine Without liability of wabloling when pressure is applied to the machine'for cracking the nut.

The plate 2 is provided at one end with a reduced extension 7 from which projects a fixed jaw 8 formed integral with. the frame of the machine and located at one-end thereof. 'llie front'depending Harige preferably extends along the frame from a point beneatli the tired jaw 'to a point beyond -tlie clamp 5, and the plate 2 projects in advance ot the Hangs d forming a anged structure of great strength and durability. The frame is provided at the 'inner rear portion of the plate 2 with a guide 9 receiving a slidable pressureA bar or member l0 and consisting1 of a rear vertical Wall ll and a top Wall l27 the guide being open at the front and the frame being provided et tlie top and bottom oi' tn seine with forwardly projecting' opper and lowersnpporting arms l and le. The ernis are formed integral with and the latter is provided at the upper and loner portions of its open front with vertical shoulders l5. The slidslole pressure bar or member lil7 wliicli is movable horizontally through the guide7 has smooth upper and lower portions or )flanges l@ fitting in the upper and lower portions of the guide and located shove and below a longitudinal series ot spur teeth l? torniing a rack and project ing at the open iront of the The projecting rack torens upper and lower shoulders 18 Winch are adapted to against tlie inner contienons Jlaces of the siwoortint ua l l face with e recess 18 to torni a Way for the 'K or connecting portion 21, are provided withY inner and outer vertically alined openings 22 and 23 for the reception of inner and outer pinsv 24 and 25, which form shafts or spindles .tor an intermediate gear 26 and an outer gear 27 mounted between the supporting arms and meshing with each other. The pins, which are provided at their upper ends with heads, are also preferably headed at their lower ends, but any other desired construction of shaft or spindle may be employed. rllhe gears 26 and 27 are provided with spur teeth and the intermediate gearing meshes with the spur teeth of the rack.

The outer spur gear is formed integral with an operating lever 28, terminating at its outer end in a suitable grip or handle 29 and adapted to be oscillated to actuate the slidable bar or member. By employing the intermediate spur gear the slidable bar or member and the lever 28 move in the same direction, which greatly facilitates a convenient and rapid operationl of the machine.

The fixed jaw|8 extends upwardly and inwardly at an inclination, and it is preferably t provided at its inner face with a concavity or seatBO to. receive one end of a nut 31, and the slidable bar or member l0 is provided with a jaw or head 32 laterally enlarged at the front side and provided with a concavity or seat 33 odset from the median longitudivnal plane of the slidable bar or member and arranged in alinement with the seat or concavity 30 and with the pitch line of the teeth of the intermediate gear and the rack of the slidable bar or member, as indicated by the dotted line a in Fig. 2 of the drawin By this construction, the power is applie to the slidable bar or member in line with the cen ter of the nut, and an accurate cracking of the same is produced. When the lever is swung horizontally inthe direction of the 55 ixed jaw, the-slidable ,bar or member is simultaneously carried in the same direction, thereby applying pressure to the nut and enablingthe same to be easily and rapidly cracked. A movement of the operating lever in the opposite direction carries the slidable bar or member in the opposite direction,

and opens the jaws of the machine.
